20:10:56 <ahaller2> ahaller2 has joined #sdw
20:11:10 <aharth> kerry: ssn, time and coverage are the topics for our meeting
20:11:26 <aharth> kerry: hierarchical geographical regions is the current use case
20:11:52 <aharth> kerry: use case 34
20:11:59 <kerry> https://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Spatial_Sampling_.28Best_Practice.2C_SSN.29
20:12:51 <aharth> kerry: we will go through the use cases and nominate requirements for the three deliverables
20:13:02 <aharth> kerry: focus is on new requirements
20:13:25 <aharth> kerry: nomination for requirement for ssn, coverage or time?
20:13:31 <kerry> q?
20:13:42 <aharth> s/nomination for/nomination of/
20:14:04 <SimonCox> q+
20:14:23 <kerry> ack  simon
20:14:33 <Zakim> + +61.4.331.2.aabb
20:14:45 <aharth> SimonCox: primarily seeing things related to best practices document
20:15:00 <ahaller2> zakim, +61 is me
20:15:01 <Zakim> +ahaller2; got it
20:15:45 <aharth> kerry: we could add a requirement around spatial and temporal representation
20:16:21 <aharth> SimonCox: unclear whether it will add a requirement on time or coverage per se, but relation between time and spatial
20:16:57 <aharth> Alejandro_Llaves: agree with simon
20:17:24 <aharth> Alejandro_Llaves: propose to remove the coverage label from use case, not the coverage as we understand it
20:17:56 <kerry> q?
20:18:05 <aharth> kerry: our coverage includes time series data, but i agree, it's changing geometry over time
20:18:21 <aharth> kerry: satellite data processing
20:18:49 <aharth> kerry: ssn and coverage are the proposed categories
20:19:58 <aharth> Alejandro_Llaves: added several requirements to the spreadsheet already
20:20:22 <aharth> ahaller2: positioning of satellite; satellite is sensor, is geo lat/long enough?
20:20:43 <aharth> kerry: descriptive satellite positioning is a challenge
20:21:17 <aharth> Alejandro_Llaves: new requirement, or in the ones we already have?  maybe metadata on positioning method?
20:21:40 <kerry> q?
20:21:55 <aharth> kerry: can we add to the requirement "and satellite position", rather than an new one?
20:22:44 <aharth> Alejandro_Llaves: there's a mark at profiling the ssn ontology
20:23:10 <aharth> kerry: profiling is a notion that arises from an xml description, similar to an extension in ontologies
20:23:31 <aharth> SimonCox: profiling would refer to a set of validation constraints
20:23:55 <aharth> SimonCox: minimum information, checking compliance (column AC)
20:24:12 <aharth> Alejandro_Llaves: what to add to description?
20:24:57 <aharth> ahaller2: qualitative measurement, observation by humans
20:25:17 <aharth> ahaller2: do we have human observations as a requirement?
20:25:57 <aharth> Alejandro_Llaves: column M (detecting qualitative events)
20:26:17 <aharth> kerry: we have citizens as senors, but not scientists
20:26:27 <aharth> kerry: column R
20:26:45 <aharth> Alejandro_Llaves: we could say citizens as sensors implies qualitative measurements
20:27:14 <aharth> kerry: qualitative measurements could also come from an algorithm
20:27:41 <aharth> kerry: citizen sensor requirement was people observations vs. machines
20:28:06 <aharth> Alejandro_Llaves: new requirement then?
20:28:21 <aharth> kerry: put column R (and maybe add ... and scientists)
20:28:32 <kerry> q?
20:29:23 <SimonCox> Which uc are we lookingat?
20:29:25 <aharth> Alejandro_Llaves: "soil moisture is only subjectively measured": unclear whether it adds qualitative measurements
20:29:42 <aharth> ahaller2: people looking at images
20:29:52 <aharth> kerry: people looking at the soil
20:30:27 <aharth> kerry: is also qualitative
20:31:04 <aharth> ahaller2: people making the measurement, does it make a difference whether based on soil directly, or via images?
20:31:48 <aharth> Alejandro_Llaves: they refer to other sources
20:31:50 <kerry> q?
20:32:20 <kerry> q?
20:32:27 <aharth> ahaller2: they could say that they use other sources for unkown values... no matter what, it's still a requirement
20:32:35 <kerry> q?
20:32:37 <aharth> kerry: agreed, i think we've caught it
20:33:10 <aharth> Alejandro_Llaves: suggest for each use case we distinguish between deliverables (ssn, coverage...)
20:33:30 <kerry> q?
20:33:48 <aharth> Alejandro_Llaves: in terms of requirements
20:34:51 <aharth> kerry: next up marine observations
20:35:17 <aharth> SimonCox: i have transcribed the use case from material provided to me (user stories)
20:35:48 <aharth> SimonCox: some ssn use, use of mobile instruments mounted on marine animals (mobile and spatial sampling features)
20:36:31 <aharth> SimonCox: column Z?
20:37:08 <aharth> SimonCox: also spatial sampling features, column F?
20:38:36 <aharth> SimonCox: number of use cases come from communities with core notions of spatial sampling
20:38:51 <aharth> SimonCox: marine, ALI...
20:39:05 <aharth> kerry: is profile here the same as in previous use case?
20:39:14 <aharth> SimonCox: these profiles are curves
20:39:27 <aharth> kerry: geometries on which samples are taken
20:39:54 <aharth> SimonCox: ssn didn't have anything on sampling, area chosen not to go
20:40:41 <aharth> kerry: relevant geometries probably covered by Z and F
20:40:47 <kerry> q?
20:40:57 <aharth> kerry: any comment on ssn aspect?
20:41:05 <aharth> kerry: now coverage, marine observations
20:42:05 <kerry> q?
20:42:14 <aharth> kerry: any comments? happy with entries in spreadsheet so far
20:42:24 <ebremer> yes
20:42:54 <aharth> kerry: next use case, marine observations data providers
20:43:02 <aharth> kerry: 3d location is suggested
20:43:29 <aharth> kerry: geo location also... anything else there?
20:43:39 <aharth> SimonCox: do we have qualitative observations?
20:43:56 <aharth> SimonCox: species identification, entry in M?
20:44:17 <aharth> kerry: M was about events
20:45:16 <aharth> kerry: species recognition done by person, looking at the images
20:46:11 <aharth> kerry: could be something new, original use case was about observing traffic jams, crowds...
20:46:33 <aharth> kerry: is species identification similar?
20:47:10 <aharth> ahaller2: maybe separation is wether observation is automatic vs. manual (algorithm vs. person)
20:47:32 <aharth> kerry: how is that related to citizen sensor?
20:48:00 <aharth> kerry: both under citizen sensing and also qualitative events
20:48:47 <kerry> q?
20:49:29 <aharth> ahaller: user story 2, last sentence
20:49:41 <aharth> s/ahaller/ahaller2/
20:49:57 <ChrisLit> ChrisLit has joined #sdw
20:50:01 <aharth> ahaller2: can we capture: we had a value before but no value now
20:50:08 <aharth> kerry: looks more like a visualisation thing
20:50:36 <aharth> kerry: do we need to cover absent values (null value measurements)?
20:50:52 <aharth> ahaller2: we have uncertainty measurements, which could cover "no"
20:51:15 <aharth> kerry: depends how it is coded up
20:51:25 <aharth> ahaller2: we could include column AA for that
20:52:07 <aharth> kerry: ok, let's do that, column AA
20:52:26 <aharth> kerry: which includes the null measurement, or null result
20:53:03 <Zakim> + +44.775.388.aacc
20:53:19 <aharth> Alejandro_Llaves: simon, did you see comments 36 and 38?
20:53:23 <kerry> q?
20:53:46 <ChrisLit> Zakim  aacc is me
20:53:58 <aharth> Alejandro_Llaves: use case description includes parts for best practice use case
20:54:20 <aharth> SimonCox: requirements have interaction with scope of best practice
20:55:02 <aharth> SimonCox: there's an encapsulation issue in general, what's the part of ssn vs. other practices or standards
20:55:04 <phila> zakim, aacc is ChrisLit
20:55:04 <Zakim> +ChrisLit; got it
20:55:20 <aharth> SimonCox: maybe first classification, then selection and cull
20:55:41 <aharth> kerry: marine observations data consumers
20:55:55 <aharth> kerry: all about best practices?
20:56:26 <aharth> SimonCox: fine
20:57:18 <aharth> kerry: last one for today was use case 38
20:58:11 <aharth> kerry: plan is to go back to single track meeting next week
20:58:44 <phila> -> http://www.sora-scc.jp/eng/index.html TPAC Venue 2015
20:58:54 <aharth> kerry: request that use case presenters go through the spreadsheet and note where columns that should have been noted
20:59:17 <aharth> kerry: will put that in an email
20:59:33 <aharth> kerry: any questions or comments?
21:00:31 <SimonCox> What is 'TPAC'?
21:00:32 <aharth> kerry: given the previous meeting with OGC, next meeting will be with TPAC in japan
21:00:58 <aharth> W3C Technical Plenary / Advisory Committee Meetings
21:01:10 <ChrisLit> W3C equivalent of OGC TC
